SCREEN-DOOR BRACE.

Specification of Letters Patent.

Patented Mar. 1'7, 1914:.

Application filed July 5, 1913. Serial No. 777,520.

To all whom it may concern Be it known that I, W. A. MORRISON, a citizen of the United States, residing at Hagerman, in the county of Grayson and State of Texas, have invented certain new and useful Improvements in Screen-Door Braces, of which the following is a specification.

My invention relates to a new and useful screen door brace, and its object is to provide a brace member which when applied to a screen door willprevent the same from sagging and hold it to a perfect rectangular form so it may not bind in its frame.

Another object of the invention is to provide a screen door brace that may be applied to a door without the use of any tools and by persons having no mechanical skill, and which may be adjusted in its proper relation to a. screen door in a minutes time.

Still another object'of the inventionis to provide a screen door brace which while it will embody no screws or threaded parts will serve to take up either a large or small amount of sag in a screen door, and which will be so constructed that one size of said brace may be applied to screen doors of various sizes.

A further object is to provide a screen door brace that will necessitate no chiseling or marring of the door to which it is applied and which will not detract from the appearance of the door.

Finally the object of my invention isto provide a device of the character described, that will be strong, durable, simple and eflicient and comparatively easy to construct, and one that may be manufactured at a very moderate expense.

With these and various other objects in view, my invention has relation to certain novel features of the construction and use, an example of which is described'in the fol lowing specification, and illustrated in the accompanying drawings, wherein:

Figure 1 is a view showing in side elevation a screen door to which my novel brace is applied. Fig. 2 is a detail isometric view showing a bracket mounted upon one of the upper corners of a screen door to which bracket one extremity of my brace rod is secured. Fig. 3 is a detail isometric view showing a bracket mounted upon one of the lateral edges of a screen door to which the other extremity of my brace rod is secured.

Referring now more particularly to the drawing, wherein like reference characters deslgnate similar parts in all the figures, the letter A denotes an elongated brace rod having hooked extremities, and B and C respectively designate two brackets engaged by the extremities of the rod A. The bracket B comprises two integral metal arms intersecting each other at a right angle, and respectively hooked over the top edge and one of the lateral edges of a screen door, an aperture being provided at the intersection of said arms to receive one of the hooks formed upon the rod A. The bracket B may be disposed ateither of the upper corners of a screen door. The red A is extended from the bracket B diagonally across the upper portion of the screen door closely adjacent to the front or rear face thereof. The bracket C ishooked upon one of the side pieces of the door frame at or adjacent to the center of said side piece, said bracket having a portion contiguous with either the front or rear surface of said side piece which portion inclines slightly upward toward the brace rod, as indicated at C. This bracket also has a horizontal portion C which is adapted to contact with the inner edge face of said side piece of the door frame. From the portion C" there projects a downwardly inclined arm G closely adjacent to the screen face of the door, the extremity of said arm being apertured to receive one of the hooked ends of the rod A.

In applying this brace to a screen door, the bracket C will preferably first be engaged with one of the vertical side pieces of the door frame. By causing said bracket C to assume a position such that the member C is horizontal, said bracket may be displaced toward the front or rear face of the frame side piece, without the hooked end of said bracket contacting with the side piece. When the parts G and C occupy their proper positions relative to the side piece, the bracket may be shifted to the position shown in the drawing bringing the hooked end of the bracket into contact with either the rear or front face of the side piece. After the bracket C is in its place upon one of the side pieces of the door frame, it is subjected to a downward displacement thereupon until the bracket B may be brought into engagement with an upper corner of the door frame diagonally opposite to the bracket C. When the bracket C is so adjusted that the rod A is subject to a tensional strain, those edges of said bracket which contact with the edge faces of the correlated frame side piece will clamp firmly against said faces and absolutely prevent any shifting of the bracket. Thus the brace will permanently occupy any position to which it may be adjusted and will completely eliminate any sag from the frame of the door.

It is to be understood that the brace may be applied either to the front or back of a screen door, and while it is preferred to mount the brace with the bracket B engaging one of the upper corners of the door, it is possible also to apply the device with said bracket engaging one of the lower corners.

The invention is presented as including all such modifications and changes as properly come-within the scope of the following claims.

What I claim is:

1. A screen door brace comprising an elongated brace rod, and a pair of brackets engaged by the extremities of said rod, one of said brackets having engagement with the door at one of its corners, and the other bracket having the form of a hook engaging one of the verticalside pieces of the door, the tension created in the brace rod by the application of the device to a door serving to cause the last mentioned bracket to clamp upon the correlated side piece of the door.

2. A screen door brace comprising an elongated brace rod, means engaging one extremity of said rod with the door at one of its corners, and a bracket engaged by the other extremity of the rod mounted upon a vertical side piece of the door and having an inclined portion engaging two horizontal portions respectively contiguous with the edge faces of said side piece, a downwardly inclined arm being formed on said bracket to engage the brace rod, the tension created in said rod by the adjustment of the brace to the door serving to cause those portions of the bracket which engagethe edge faces of said vertical side piece to clamp against said faces. 7 7

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
